Sun

Solar Symmetry and Balance

The CERES satellite dataset is a never-ending source of amazement and interest. I got to thinking about how much energy is actually stoking the immense climate engine. Of course, virtually all the energy comes from the sun. (There is a bit of geothermal, but it’s much less than a watt per square metre on average so we can ignore it for this type of analysis).

So let’s start from the start, at the top of the atmosphere. Here’s the downwelling top of atmosphere (TOA) solar energy for the northern and the southern hemisphere:

The Source Of The Heat

Over at Dr. Judith Curry’s always excellent blog, she has a post headlined by a question, viz:

What are the main sources of heat that account for the incremental rise in temperature on Earth?

Let me start by saying that this is a horribly phrased question. Consider a parallel question:

What are the main sources of heat that account for the incremental rise in my body surface temperature when I put on a jacket?

I. Introduction

The sun is the natural source of heat and light for our planet. Without our sun, the earth would be a cold dead planet adrift in space. But the sun is not constant. It changes and these subtle changes affect the Earth’s climate and weather.

At the end of solar cycle 23, sunspot activity declined to a level not seen since the year 1913. [Comparing Yearly Mean Total Sunspot Numbers1]

The Solar Harbinger

The people of Canberra are the richest in Australia so they voted in a provincial government that proved how virtuous they were by increasing the proportion of their power supply that came from wind and solar sources. As a consequence, the cost of power went up and the people of Canberra have responded by seeking out warm public buildings in the current southern winter. Respiratory disease load increases in winter and so no doubt there will be some deaths caused by the government’s virtue signalling.

Hundreds of thousands of people in first-world-country Germany have gone off grid because they can’t afford power any more. Of course heat kills too and the biggest heat-related, first-world die-off in recent years was in Europe in 2003. As Dave Rutledge wrote in 2015, “During the great European Heat Wave of 2003, 70,000 people died, most of them indoors. This is a horrible way to die. The people who were indoors could have been saved by a $140 Frigidaire window unit, but only if they could afford to pay for the electricity.”

Climate Scientist Josh Willis Shows You How to Deal With Your Climate Change Denying Uncle

Josh Willis, of NASA JPL, has a new video out entitled, “Straw Men of the Apocalypse – How to deal with your climate change denying uncle.”

clip_image002

Notice that “catastrophic” is apparently not scary enough, these days. Global warming is now “the Apocalypse.”

The video starts out with two guys crawling along the parched ground under the blazing desert sun. One of them says to the other, “We’re gonna die out here, man. If only society had done more to fight climate change.” And it goes downhill from there.

The Difference Between Energy, Work and Power – and Why it Matters to Climate Prediction

How often have you heard claims that a warmer [climate] will be more energetic – that we shall all experience more violent storms, more rainfall, more storm damage, because the atmosphere is “absorbing more energy”?

Such claims are based on a fundamental misunderstanding of the nature of energy.
